Description

Technical Field

[0001] This utility model relates to the technical field of cam dividers, and in particular to a self-lubricating cam divider. Background Technology

[0002] A cam divider is a precision mechanical device that uses the rotational motion of a cam to accurately divide a workpiece. Cam dividers are often used when dividing continuously moving materials.

[0003] During the use of a cam divider, continuous operation may cause its temperature to rise and the internal pressure of the oil tank to increase, leading to the gradual consumption of lubricating oil and a decrease in its operating efficiency. Currently, the common method is to manually replenish the lubricating oil. While manual replenishment can prevent the lubricating oil inside the divider from being completely depleted, frequent oil replenishment not only requires the equipment to be stopped but also consumes excessive manpower. Therefore, it is still difficult to completely prevent the cam divider from losing its operating efficiency due to the depletion of lubricating oil. Utility Model Content

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] like Figures 1-4 As shown, the self-lubricating cam divider of this utility model includes a cam divider 1 and a self-lubricating mechanism 2.

[0018] The self-lubricating mechanism 2 includes a first spring 23, a top plate 24, a graphite tube 25, a fixing plate 26, and a fixing block 27. A first mounting groove 21 is provided on the cam divider 1, and a first limiting groove 22 is provided within the first mounting groove 21. The first spring 23 is disposed within the first mounting groove 21. The top plate 24 is connected to the other end of the first spring 23. The graphite tube 25 is disposed within the first mounting groove 21. The fixing plate 26 is disposed on the graphite tube 25. The fixing block 27 is disposed on the outer wall of the fixing plate 26. A limiting tube 28 is sleeved on the outside of the graphite tube 25, and a second mounting groove 29 is provided on the inner wall of the limiting tube 28.

[0019] When using the cam divider 1, the rotating fixing plate 26 removes the outer wall fixing block 27 from the first limiting groove 22, and then places the graphite tube 25 in the second mounting groove 29 on the inner wall of the limiting tube 28 and puts the limiting tube 28 into the first mounting groove 21, so that the outer wall of the cam 12 contacts the graphite tube 25 in the limiting tube 28. Then the fixing plate 26 is put back and fixed again. When the cam divider 1 is running, the rotating cam 12 will rub against the inner wall of the graphite tube 25. At this time, the graphite will form a uniform graphite lubricating film on the surface of the cam 12, separating the two friction surfaces and avoiding direct contact, thereby greatly reducing wear and friction resistance. At the same time, the graphite particles formed by friction can still play a certain lubricating role, thus achieving a self-lubricating effect.

[0020] In one embodiment of this application, such as Figure 1 As shown, the cam divider 1 includes a housing 11, a cam 12, an output shaft 13, and a transmission rod 14. The cam 12 is disposed inside the housing 11, the output shaft 13 passes through the outer wall of the housing 11, and the transmission rod 14 is connected to the output shaft 13. During the use of the cam divider 1, the transmission rod 14 drives the output shaft 13 to mesh with the cam 12, converting continuous input rotation into intermittent output motion.

[0021] In one embodiment of this application, such as Figure 3As shown, an installation mechanism 3 is provided on the output shaft 13. The installation mechanism 3 includes a ball bearing 33, a connecting ring 34, a limiting ring 36, and a second spring 37. A first connecting groove 31 is provided at one end of the output shaft 13, and a limiting hole 32 is provided on the inner wall of the first connecting groove 31. The ball bearing 33 is disposed in the limiting hole 32. The connecting ring 34 is sleeved on the outside of the output shaft 13. The second spring 37 is sleeved on the outside of the output shaft 13, and both ends of the second spring 37 are connected to the connecting ring 34 and the limiting ring 36, respectively. A second limiting groove 38 is provided on the outer wall of the transmission rod 14. A control shell 35 is provided on the outside of the limiting ring 36. A fixing ring 310 is provided on the outside of the output shaft 13.

[0022] When it is necessary to connect the transmission rod 14 to the output shaft 13, the control housing 35 is pulled towards the housing 11. The control housing 35 drives the limiting ring 36 to open from the limiting hole 32 at the opening outside the output shaft 13, releasing the restriction on the ball 33. Then, the transmission rod 14 is inserted into the first connecting groove 31 at one end of the output shaft 13. At this time, the ball 33 will be squeezed into the limiting hole 32. Then, after the second limiting groove 38 on the outer wall of the transmission rod 14 is aligned with the limiting hole 32, part of the ball 33 will fall into the second limiting groove 38. At this time, the control housing 35 is released, and the limiting ring 36 in the control housing 35 will be ejected to the opening of the limiting hole 32 by the action of the second spring 37, thereby completing the fixation of the transmission rod 14.

[0023] In one embodiment of this application, such as Figure 4 As shown, a limiting component 39 is provided on the output shaft 13, which includes a limiting block 392 and a limiting post 393. A sliding groove 391 is formed on the outer wall of the transmission rod 14. The limiting block 392 is disposed within the first connecting groove 31, and a limiting post 393 is provided at one end of the output shaft 13. A second connecting groove 394 is formed on the outer wall of the transmission rod 14. When installing the transmission rod 14, the limiting block 392 in the first connecting groove 31 and the limiting post 393 at one end of the output shaft 13 are respectively engaged into the sliding groove 391 on the transmission rod 14, preventing the transmission rod 14 from spinning freely within the first connecting groove 31.

[0024] The working principle of this utility model is as follows: When using the cam divider 1, the rotating fixing plate 26 removes the outer wall fixing block 27 from the first limiting groove 22, and then places the graphite tube 25 in the second mounting groove 29 on the inner wall of the limiting tube 28 and puts the limiting tube 28 into the first mounting groove 21, so that the outer wall of the cam 12 contacts the graphite tube 25 in the limiting tube 28. Then the fixing plate 26 is put back and fixed again. When the cam divider 1 is running, the rotating cam 12 will rub against the inner wall of the graphite tube 25. At this time, the graphite will form a uniform graphite lubricating film on the surface of the cam 12, separating the two friction surfaces and avoiding direct contact, thereby greatly reducing wear and frictional resistance. At the same time, the graphite particles formed by friction can still play a certain lubricating role, thus achieving a self-lubricating effect. When it is necessary to connect the transmission rod 14 to the output shaft 13, the transmission rod 14 is connected to the housing. Pulling the control housing 35 in the direction of 11 causes the limiting ring 36 to open from the limiting hole 32 at the opening outside the output shaft 13, releasing the restriction on the ball 33. Then, the transmission rod 14 is inserted into the first connecting groove 31 at one end of the output shaft 13. At this time, the ball 33 will be squeezed into the limiting hole 32 first. Then, after the second limiting groove 38 on the outer wall of the transmission rod 14 is aligned with the limiting hole 32, part of the ball 33 will fall into the second limiting groove 38. At this time, the control housing 35 is released, and the limiting ring 36 in the control housing 35 will be ejected to the opening of the limiting hole 32 by the action of the second spring 37, thereby completing the fixation of the transmission rod 14. When installing the transmission rod 14, by inserting the limiting block 392 in the first connecting groove 31 and the limiting post 393 at one end of the output shaft 13 into the sliding groove 391 on the transmission rod 14 respectively, the transmission rod 14 will not spin freely in the first connecting groove 31.
